I tried to build a singleton class, but it doesn't work. The function i used do not return anything.
[url=http://pastie.org/2019522]Code on Pastie.org[/url] (Hope it works)

<?php
//-----------------singleton class------------------------
final class SearchResult {

private static $instance = NULL;

private function __construct() {
}

public static function getInstance() {

if (self::$instance === NULL) {
self::$instance = new self;
}
return self::$instance;
}

public function getResultTable(){

   return 'Test- Result';
}

}

// try to use the class
// [...]
function Test(){
   $searchResult = SearchResult::getInstance();
   return 'Result: '.$searchResult->getResultTable;
}
// [...]

?>

You forgot the brackets after your function call.
